This is actually not true at all times or for all sharks. It is true that most sharks need moving water in order to breathe, but there are underwater currents where sharks can stop, because the water is moving around them.
most sharks dont have homes that are built they never stop swimming because if the did the would sink to the bottom of the water and get stuck
If sharks stop swimming,then they sink, but the nurse shark is an exception
Sharks finning is a cruel practice and is illegal in most countries. After getting finned still alive sharks are thrown back in ocean. These sharks sink to the bottom of the ocean because they can not move effectively and die as a result of suffocation or eaten by other predators.
yes some boats.
because sharks have to swim to breath so if they dont swim then they dont breath causeing them to sink and die. because sharks have to swim to breath so if they dont swim then they dont breath causeing them to sink and die.

yes or they can drown and die if they sink
A cannonball.
Because in salt water the salt will be everywhere and it will be smooth
I have researched ALOT on sharks and I do not think that a cookie cutter shark could sink a submarine.It isn`t possible because a suubmarine is made of metal and I don't even think that cookie cutter sharks could bite through metal.I hope that this answers you question!:)
only if...
First they float for a while and then they sink. no _____________ They don't simply float forever; things (such as other sharks) come and bite bits from them until the internal gases are released and then the creature deflates and joins other dead creatures on the seabed. If this were not so, we'd be sailing through an ocean of acquatic deceased bodies. _____________
